AUTOMATIC VALVE.

Application led October 27, 1916.

To all whom t may concern:

Be it known that I, WILLIAM JAMns HAYNES, a citizen of the UnitedStates, residing at the city of St. Louis andl State of Missouri, haveinvented a new and useful Automatic Valve, of which the following is aspecification.

This invention relates to improvements in automatic valves andconsistsin the novel design, arrangement and combination of parts in such avalve as hereinafter more fully disclosed.

An object of the invention is to provide a valve ladapted primarily tocontrol the supply passage to a tank or container whereby apredetermined level of liquid may be maintained in the tank.

Another object of the invention is to produce a valve of simple anddurable construction which is weighted to maintain the valve in openposition, and which is operated to closed position after a predeterminedlow of water through the valve.

Additional advantages .attainable from the present construction will beclearly apparent to those skilled in the art to which -this inventionrelates without specific mention from the following detailed disclosuretaken in connection with the accompanying drawing, in which- Figure 1 isan elevation of a tank or container equipped with a supply passagehaving the valve of the present invention applied thereto. Fig. 2 is aplan view of the valve structure detached and having portionsbrokenaway. Fig. V3 is a front end elevation ofthe valve partially insection to more fully disclose certain features of the construction.AFig 4 is a vertical. section through the valve taken .substantially onthe line 4-4 of Fig. 2. Fig. 5 is a vertical section through the valve.taken substantially on the line 5-5 of Fig..2. Fig. 6 is a perspectiveview of the arm controlling the valve plug.

1n the embodiment of the invention illustrated in the drawing, the valveis shown applied to an inlet passage 1 of a tank 2. The valve propercomprises a casing 3 which is substantially in the form of a,-

T-shaped union, that is to sav it has a tubu-,L

wall of which is projected upwardly forming the extension 5. The mainbody of the extension 5 is rectangular in form and comprises a squaredbody cast integral with the body 4 and having formed at the topintegrally therewith a. polygonal casting 6 having a Vcylindricalthreaded opening 7. The body 4 has polygonal ends 8 and 9 respectively,said ends being threaded interiorly. The polygonal portions 6, 8 and 9respectively are provided for wrench engagement so that the .valve maybe attached to the connections. The body. portion 4 has a transversepartition wall 10 integrally formed therewith, said partition wallhaving an axial port or opening 11. The end of the supply passage 1.discharges into the end of the body 4 beyond the partition 10, saidsupply passage being in threaded connection with the end 8 of the body.Upon the inner wall of the body 4 adjacent to the inne-r face of thepartition 10 are formed ribs or lugs 12, the inner edges of said lugsbeing rounded so as to receive and support the valve plug 13.

The valve plug 13 vis a cylindrical body having a flat forward face anda rounded projection 14 from its rear face. There is a threaded openingin the front face of the valve plug 13 adapted to receive the screw 15by means of which a rubber washer or gasket 16 is held against the frontface of the valve plug. The valve plug is adapted to slide to and awayfrom the partition wall 10 thereby controlling the inlet port 11.

The front wall of the extension 5 has an exteriorly threadedhollowprojection 1'( designed to receive the packing nut 18and to formapacking vgland with the .packing 19 around the casting 20. The casting20 comprises al hollow cylindrical section 21 which is adapted to bereceived within the packing glandcomprising the parts 17, 18 and 19,said .section 21.1iaving an inwardly extending squared portion 22 at theend of which is a rounded projection 23 having a depression 24 on itsinner face. The projection 23 is adapted to seat in a recess formed in aboss 25 on the rear wallof the extension 5 of the main valve casing,there being within the recess and between a wall of the boss a ball larhorizontally disposed body 4, the upperjjji The casting L0 has anupwardly extendto close the inlet passage when u predetermined quantityof liquid enters said container from the valve easing, and to autoingWitnesses.

In Witness whereof, I have signed this speelioetion 1n the presence oftwo subscrlb- -matieally release said valve body from the WILLAM JAMESHAYNES. 'a intake opening when the level of the Water Witnesses:

in the tank drops below a predetermined N. G. BUTLER, height,substantially as specified. C. A. BECKER.
